MACHINE FOR FILLING MARSH LAND.

SPECIFICATION forming part of Letters Patent No. 268,710, dated December 5, 1882.

' Application filed October 12, 1882. (No model.)

To all whom it may concern Be it known that I, FRANK MOORE, a citizen oi the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Machines for Filling Marsh Lands, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention. relates to improvements in filling up marshy land, and in the discharge of mud-scows orlighters from dred gin g-machines.

In the drawings forming part of this speci fication, Figure l is a side elevation in section of a mud-scow, and in the rear thereof a float or vessel provided with steam-power and pumps. Fig. 2 is an end elevation of the "scow in-section and of the float with some of the parts removed, and also having a portion of one end broken away. Fig. 3 is a side elevation of the mud-shield and its removable casing. Fig. 4 is asection of the shield and casing, taken on the line of a: w of Fig. 3. Fig. 5 is a side elevation of a piece of marsh land submerged, with a short section of the bagging, showing the means to hold it in the proper position.

B is the mud-scow or vessel, having a floor the center, where there is located a vertical tube, H, having perforations of suitable size, for the purposes hereinafter described. Surrounding the tube His another of larger diameter, I, provided withhandlest or other means to facilitate its ready removal. The removable tube 1 is intended to provide an open space in the excavations contained in the scow, in order that the perforated tube H may be easily inserted therein, and thus obviate the necessity of providing apermanent strainer in each scow used in carrying away the excavations from a dredge.

A is a float or scow, in which is located suitable steam-power, and is provided with two force and lift pumps, of any construction, adapted to the purposes required.

The pump 0 is provided with pipes E for suction and E for discharge. The pipe E may be flexible, and is introduced into the tube H. The pipe E may also be of flexible material and constructed in removable sections, so as to discharge its contents at any convenient distance from the vessel A.

The pump D has its suction-pipe D carried through. the bottom or side of vessel A into the water in which the vessel floats, and its discharge-pipe G is fitted with one or more nozzles, which may be held and operated,and directed by hand, as shown iu the drawings, or in any other convenient manner.

This machine is intended to be used to deposit the excavations from a dredge inside of a bulk-head into the water, or on flats or depressions requiring to be raised or filled-with earth through pipes or sluices, as shown in the drawings. It can also be used for convey- 6 5 in g the earth or fillings from a hill or elevation, on shore, into hollows or depressions with great economy and rapidity.

In a case where there is no bulk-head or inclosing wall, a substitute for the wall can be used-such as a piece of jute or bagging cloth of sufficient width or depth to reach the surface of the water when the lower edge is resting on the bottom, held down by weights, and i the cloth sustained by vertical stakes placed 7 at intervals necessary'for the purpose, this being movable and placed in position very quicklysay to inclose one hundred square yards, more or less, as may be wished, at one time. This inclosure will prevent any current or: 86

tide that there may be from having any effect inside the inclosure while it is being filled.- The same means can be used to inclose another space by taking up and putting down the stakes and cloth in another place, and so on until the required height of filling the whole area is com pleted.

In Fig. 5 is represented a piece of land submerged and also a short section of baggingcloth, 0, which may be strengthened by abolt- 9o rope, KK, at top and bottom. The upper rope, K, is attached to the stakes L, and the lower rope, K, may or may not be secured thereto. The lower rope may be provided with weights W, attached permanently; or 5 and to strain all matter which may interfere I 1. In a mud-scow having its floor inclined with the proper action ofthe machine. I Should the excavations contained in the scow B be too thick to flow into the suction-pipe E, they can be liquefied by the introduction of water by means of the pipe G. It has been found in practice that a pump constructed for the purpose can lift and discharge soil which has been reduced to a plastic state by the introduction of about fifty percent. of water, and it is intended to use a pump of such construction as a part of the means of carrying out this method of filling marsh lands.

It is obvious that the pumps 0 and D may be located on shore, and that the same results could thus be attained as by having them on a float.

Having described my inventiomwhat I desire to secure by Letters Patentand to claim at an angle toward a central point, the combination of a suction-pipe, E, and perforated tube H with a removable tube, I, substantially as described, and for the purposes set forth.

2. In a mud-scow, the combination of a lift and force pump, 0, adapted to lift and discharge plastic material, with the suction-pipe E, perforated pipe H, and removable casing I, as shown and described, and for the purposes set forth.

3. In a mud-scow, the combination of outer casing, I, with the perforated tube H, as described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK MOORE.
